In the world of commercial and private road transport, medium and heavy trucks are the backbone of global and local economies. They have the responsibility of transporting goods and materials over vast distances. On their way, they face a variety of different challenges. As such, they require a high level of efficiency and stable performance. At the heart of this complex system lies a crucial key element, but it is considered to be only a piece of consumer rubber, but in fact it represents a highly important and crucial investment and strategic currency: tires (tires) are not just a piece of rubber, but the barrier between the truck and the road on which inventions started Cars, trucks and all modern vehicles are the vital link that translates engine power and torque into actual movement on the ground. It is the movement that drives trucks and carries goods and luggage from place to place, carrying that global economy or a large part of it.
Because tires (tires) are made of rubber, they have different characteristics and capabilities. There are tires that are able to withstand increased heat and pressure, and there are other tires that are able to deal with extreme cold, ice and very low temperatures. These different changes are followed by changes in fuel consumption levels as well. There are tires that are able to save fuel consumption significantly, while there are tires that increase fuel consumption and increase the load on the engine. All these differences and differences are due to different environments and different climates from one country to another, which necessitated the existence of various tires compatible with the environment that works Thus, it is easy to deal with tires and know the right type for trucks and cars, but we should not forget that these criteria may decrease with tire consumption. Worn tires reduce the efficiency of saving fuel by up to 20%. Therefore, the process of choosing a tire does not stop only after purchasing it, but goes beyond that because the life cycle of tires must be managed properly to extend the life of tires and reduce maintenance costs, which enhances the performance of the truck or the logistics fleet.

As such, it is a national company working to provide a suitable local product Exactly for the environment in which trucks operate.
How to read and understand the symbols on the sidewall of the tire?
The sidewall of a tire is the personal identity of a tire, but on the other hand, it is considered by many to be a mystery that cannot be understood or read. Through the following lines, we will learn what these symbols are in detail and know their meaning and what they symbolize. They contain all the basic tire information that shows its characteristics and capabilities.
We start with the dimensions of the tire and its structural structure. The main focus for understanding these dimensions is the number (315/80). The first three numbers express the width of the tire in mm. It represents the distance between the walls of the tire, while the second number (80) is the aspect to width ratio. As in the example, the height of the tire is 80% of its width of 315 mm. This indicator is very important because it affects the stability and comfort of the truck while driving on long trips. The lower this percentage, the more stable the tires are in sharp turns, and vice versa if the percentage rises. R22.5) is also written on the side of the tire and is an abbreviation of the word “Radial”, which means that the inner layers of the tire are wrapped radially or vertically at a 90-degree angle relative to the direction of movement.
Radius tires are the most common in modern trucks due to their many unique features that are more advanced than traditional tires, including a lower level of rolling resistance, improved fuel efficiency, and increased stability on the road at high speeds. The last number (22.5) indicates the wheel diameter in inches and determines the size of the wheel on which the tire can be installed. In truck tires, the common wheel diameters vary to include 22.5 inches, 20 inches, 19.5 inches and 17.5 inches.
Load index and speed index
After the dimensions of the tires, there is a new set of numbers, symbols and letters that determine the capabilities of the tire in terms of load and speed. For example, “156/150L” in our current example, the number (156) represents the load index corresponding to the weight in kilograms, determining the maximum load allowed for this tire. The weight is determined by the tables approved by the tire manufacturer, which are fixed numbers for companies, countries and traffic departments around the world. It is worth noting that truck tires must have two numbers in the load index field. The first number indicates the capacity of the tire in the case of Using it individually, while the second number is the equivalent, but in the case of double tires, this is very important for logistics fleet managers in order to ensure that the maximum load on each axle of the truck is not exceeded and that you are not subject to double fines. The letter “L” indicates the maximum speed allowed by the tire at full load.
Additional symbols on the frame
More symbols can clearly be seen on the side of the tire, but what do these symbols mean? The answer is that they are very important symbols. The first is “LT”, which briefly indicates that these tires are used in “Light Truck”, while the “C” indicates the word “Commercial”, which means that the tire is commercial and this determines the main purpose of using this tire. You can also find the date of manufacture of the tire (Kufr), which consists of four digits, the first two of which refer to the week of manufacture and the last two to the year of manufacture, for example “0223”, meaning that the tire was made in the second week of 2023 This date is very important because the tire is often unusable after five years from the date of manufacture. Despite the condition of the tire, the consumer period expires even when the tire is not used because the chemical components start to break down and damage automatically.
Other symbols written on the side of the tire include the temperature rating that the case can withstand, which is called “Temperature Grade”, which determines the ability of the tire (case) to dissipate heat and the ability to deliver. It comes in three levels from A to C, starting from the best to the least efficient at high temperatures and high speeds. In addition, another classification is the grip rating, which indicates the ability of the tire to hold on wet and smooth surfaces. This rating ranges from AA to C. You may also find other symbols such as “TL”, which refers to the English word “Tubeless”, which means that the tire has no internal tube, Or the “TT” symbol, which means the tire is designed to be used with an inner tube.
It's a small symbol on the side of the tire but it's responsible for the fate of your truck!
What is the relationship between tire pressure and wear
The data clearly shows that air pressure inside the tire is not just a number that must be adjusted. It is one of the main factors that determine the wear pattern on the tire and directly affect the efficiency and safety of the truck. Improper pressure can cause disasters as it directly determines the extent of wear to which the tires are exposed. In the event of a sharp drop, the tire becomes more in contact with the road, making the largest area of the tire wear out. This is related to the physics of contact between the road and the tires.
When the tire is inflated with less pressure than recommended, the contact between the edges of the tire and the road increases, while the contact decreases in the middle. This uneven distribution of load leads to rapid and excessive wear of the outer edges, which is known as “wear on the shoulders.” Moreover, an uninflated tire tends to generate excessive heat due to increased friction during rolling, which ultimately leads to increased fuel consumption.
On the other hand, when the tire is inflated with a significantly higher pressure than recommended, the exact opposite occurs. The load is concentrated on the middle of the tire, causing swelling and sharply reducing the area of contact of the tire with the road, making all the load focus on the middle of the tread, while the outer edges remain relatively intact. This pattern of wear not only reduces the life of the tire, but also affects stability and grip, especially in wet road conditions, because the effective contact area with the road is significantly reduced.
If you want to understand the deep relationship between the internal pressure (tires) and the levels of damage, this is not easy. A simple procedure such as adjusting the air pressure inside the tire has an impact on safety, consumption and the life of the tire. The wear caused by air pressure is one of the worst types of wear as it causes strong vibrations and loud sounds because it is uneven on the entire surface of the tread, which poses a danger to the suspension system and other systems. In conclusion, saving in not performing periodic or daily tire inspection is only a false saving. Its results show high maintenance costs due to damage to tires or load and suspension systems, Therefore, daily maintenance, daily inspection and adjusting the pressure of tires while they are cold are the best things that can be done to make tires work well without side effects that cause downtime or terrible accidents on commercial highways.
Internal air pressure.. A simple step that saves significant costs!
